The short answer to this question is "maybe." It depends on what your accountant says. The IRS allows for deductions for travel in order to do "charity work" (not the language we use to talk about our Nicarguan partnerships, but that's the language the IRS uses). Some of your trip fee is related to your travel expenses (room, board, in-country transportation), some provides support for the specific projects your group is working on, and some provides administrative support for JustHope. If you would like to deduct your trip fee, talk with your tax professional about it. JustHope provides email receipts for trip fees that can be used for tax reporting.
